Techne PRT's
Techne Home
Our PRT's offers proven and reliable performance for your
critical temperature measurements. They can be used with our Tecal Accu-Temp indicator or any comparable model. Both models include an ITS-90 calibration
(NIST traceable) certificate with coefficients and resistance vs. temperature
table. The WSP660 gives an SPRT level of performance and specifications at an affordable price, while the 300 deg.C model is an Industrial RTD designed for lower accuracy measurements.

660° C Working Standard PRT |
 |
Model WSP660 PRT's are assembled using our special wire wound RTD
elements, assembled into inconel sheaths. The WSP660 PRT has similar
accuracy and long-term stability specifications you would find in much
higher priced Primary standard PRT's. The WSP660 PRT can be
used as a reference standard in calibration baths, furnaces, fluidized baths, dry block
calibrators and other any other temperature calibration work requiring a
high level of accuracy and repeatability. Combine with |

300° C Working Standard PRT |
|
|
The model TI913 RTD is
a good choice for lower temperature range work at a lower accuracy. The
sheath is of stainless steel construction with a mineral insulated .385
alpha RTD. The TI913 can be used as a working standard in calibration
baths, furnaces, fluidized baths, dry block calibrators or for any other
temperature calibration work. |
